Enabling single Data processors in Privacy settings will fail

Steps:
– Go to the frontend.
– Instead of accepting all, go to the privacy settings.
– The privacy settings modal will open.
– Enable a single, optional data processor.
– Click accept.

Verify:
– Look at the “wpgdprc-consent-*” cookie.
– all data processors are set to “declined”.

Reason:
1. AbstractAjax::validateData()
– “json_decode( $data )” will decode the string as an array of integers — e.g. {“checked”:[3]}
– “Helper::sanitizeStringArray( $data );” will sanitizes the data as an array of strings — e.g. {“checked”:[“3”]}

2. ConsentCookie::buildResponse()
– “in_array( $object->getId(), $data[‘checked’], true )” has the strict parameter enabled.
– The condition will fail because “$object->getId()” is an integer and “$data[‘checked’]” is an array of strings.
